Patent CA-2056722-A1 (CA)
Inventor: KUDOH KAZUHIRO
IPC: G08B5/22
Filed: 1991-11-29
Abstract: A display-equipped radio pager according to the present invention provides a detecting circuit 6 to detect keywords which are distinguished by a specific mark such as double quotation marks for each message received, and another detecting circuit to detect whether the received keyword is already registered in the memory or not.  The pager also provides a registering circuit to automatically register the received data related to the keyword  into the memory.  When a signal including its own call number is received, a call alert is issued, and a display means 8 displays a message included within that signal on a display 9.  In addition, when a keyword is detected, the detecting circuit 14 detects whether the received keyword within that message is already regis-tered in the memory or not and, if the same keyword is detected, a registering circuit 15 then registers the data related to the keyword within the message into the memory 10 as additional data.  When a personal name is registered in the memory 10 as a keyword and the corre-sponding address is registered as data of the keyword, this stored information is treated as a part of the record of an electronic pocket notebook and, when a user wishes to read out the contents of the memory 10 by keying in a keyword from the keyboard 13, the LCD driver 8 reads out the information registered in the memory 10 and displays it on the LCD 9.

Abstract: A demolition hammer intended for attachment to a bracket or the like. The demolition hammer includes an adapter bracket which connects to the arm of a backhoe in place of the conventional bucket of the backhoe, and a hammer head spaced apart from the adapter bracket by a hammer spring arm cantilevered or pivotably mounted with respect to the adapter bracket. Repeated operation of the backhoe hydraulic cylinder which normally pivots the bucket will instead move the hammer into repetitive impacts with the concrete or other work surface undergoing demolition. The flexibility of the hammer spring adds a whipping action which increases the effective impact of such movement.

Abstract: A tire with reduced tire noise includes a tread having a plurality of base pitches placed about the circumference   of   the   tire   in   at   least   one circumferential section.  According to one aspect of the invention, the base pitches have three different pitch lengths  which  form  a pitch  sequence  around  the circumference  of  the  tire  in  each  circumferential section.  The base pitches are arranged such that the transitions between the base pitches with the smallest pitch lengths to the base pitches with the largest pitch lengths are between about 15% and 30% of the total number of transitions between base pitches in the pitch sequence.  Additionally, the smallest and largest base pitches each comprise between about 35% and 40% of the total number of base pitches around the circumference of the tire.  The above factors, when coupled with no more than three consecutive base pitches having the same pitch  length  being  arranged  adjacent  one  another, provide a tread with reduced tire noise.

Abstract: Abstract of the Disclosure An apparatus for creating an optical noise of a predetermined bandwidth that uses an optical amplifier which amplifies optical noise components and produces unpolarized optical noise by spontaneous emission, a mirror to reflect the optical noise components back to the optical amplifier and a filter that filters out optical  noise  components  outside  the  predetermined optical  bandwidth.   The filter  is  located  so that optical  noise  components  passed  by  the  filter  are amplified in the optical amplifier during an additional amplification.   Optionally,  a polarizer and Faraday rotator are used in the apparatus.  The optical noise created in the optical amplifier is polarized in the polarizer after two amplifications,  rotated  in the Faraday rotator, then amplified two more times before leaving the apparatus.
